It's possible that the data stored for Story Maker may have become corrupted if the issue persists after performing a hard reset. In this case, unfortunately you will need to manually back up the data on your device and perform a security wipe which should remedy the issue. I would normally recommend backing up via BlackBerry Link, but the corrupted data may be included in such a backup and therefore cause the issue to reappear after restoring.

do a complete wipe of the phone and install.. Of course do a backup via link, also even save all your data, video, pictures to a hard drive.
The complete wipe with the fresh installed updated BB10 OS made my phone great, Story Maker works A++* and you will notice more device storage. Because everything was install clean and efficient . Hope it helps
